B-3 FUEL PRESSURE CHECK (Page 1 of 2)
STEP
1) Release fuel pressure from fuel feed line.
2) Install fuel pressure gauge.
3) Check fuel pressure by repeating ignition switch ON
1
and OFF.
Is fuel pressure then 270 – 310 kPa
(2.7 – 3.1 kg / cm
Is 200 kPa (2.0 kg / cm
2 sure retained for 1 minute after fuel pump is stopped at
step 1?
1) Start engine and warm it up to normal operating
temperature.
3 2) Keep it running at specified idle speed.
Is fuel pressure then within 200 – 240 kPa
(2.0 – 2.4 kg / cm
Is there fuel leakage from fuel feed line hose, pipe or
4
their joint?
Was fuel pressure higher than specified value in Step
5
1?
1) Disconnect fuel return hose from fuel pressure
regulator and connect new return hose to it.
2) Put the other end of new return hose into approved
6
gasoline container.
3) Operate fuel pump.
Is specified fuel pressure obtained then?
